Wood tar pitches are generated as by-products by the charcoal manufacturing industry. They have a macromolecular structure constituted mainly by phenolic, guaiacylic, and siringylic units common to lignin. Due to their characteristics, biopitches are been investigated as precursors of carbon materia
The viscosity of coal-tar pitch (CTP) mixtures with pulverulent graphite was determined between 100 and 180°C. The pitch precursor viscosity dependence on temperature obeys an equation proposed by Williams, Landel and Ferry (WLF equation), whose coefficients could be qualitatively related to the che
A commercial impregnating coal-tar pitch was air-blown at 275°C for 10, 18, 25 and 30 hours. Isotropic pitches were produced with softening points ranging from 140 to 210°C. The parent and treated pitches were characterized by elemental analysis, Fourier transform infrared, solubility in toluene and
